An assessment approach in regard to tailings dam break would be analyzed and established in aspects of life, property and environment & resources loss in the essay. Tailings bam break hits local social economy varying with region as a result of particular and specialized space diversity. With the simple and practicable approach, it is quite reasonable to accomplish quantitative assessment of risk as well as review controlling priority to potential risk arising from tailings reservoir.

Tailings Reservoir

The tailings dam is a very important component part in mine production facilities. Meanwhile, it is a potential major risk source with high potential energy. Through collecting many accidents of the tailings dam, it is showed that accident type of the tailings dam mainly is dam-break, damage of drainage system, leakage of tailings, etc. On the basis of this analysis, the main causes of dam-break are slope instability, breaking construction rule, unusual rainfall, etc. The automatic safety monitoring and management system of the tailings reservoir (ASMMS) is a powerful measure for mine safety production. The basic frame of the ASMMS is proposed. The main contents and key problems of the ASMMS are also analyzed. It can provide a strong theoretical and technical basis for the safety and management of the tailings dam.

Assessing the potential risk of mission via analyzing the product life cycle data (APRPD) is a useful aerospace product quality assurance tool. The structure of aerospace product parameters has become increasingly complex and correlations exist among the multi-dimensional parameters. It is necessary to take the correlation into account when deriving an effective APRPD analysis. In this article, a density-based APRPD approach for multi-dimensional is proposed. The local outlier factor (LOF) of the observation is investigated and according to the LOF value the potential risk are assessed. This non-parametric APRPD approach can be used to analyze non-linear correlated data and does not require any data distribution assumption. The performance of the approach is demonstrated via a numerical case.

Tailings dam is a potential risk source in the metal mines, once the tailings dam break, it will not only lead to tremendous loss in people’s lives and property, but also result in serious environmental pollution. Basing on the accidents of tailings dam failure at home, the dam failure causes are analyzed, some technology and management suggestions about decreasing dam-break accident are put forward, which provide reference for safety management to tailings dam.

Event Occurrence

Purpose This study aims to argue that in the case of quantitative security risk assessment, individuals do not estimate probabilities as a likelihood measure of event occurrence. Design/methodology/approach The study uses the most commonly used quantitative assessment approach, the annualized loss expectancy (ALE), to support the three research hypotheses. Findings The estimated probabilities used in quantitative models are subjective. Research limitations/implications The ALE model used in security risk assessment, although it is presented in the literature as quantitative, is, in fact, qualitative being influenced by bias. Practical implications The study provides a factual basis showing that quantitative assessment is neither realistic nor practical to the real world. Originality/value A model that cannot be tested experimentally is not a scientific model. In fact, the probability used in ISRM is an empirical probability or estimator of a probability because it estimates probabilities from experience and observation.

The Liguria Region in Northern Italy is characterized by a wide geological and geomorphological variety, encompassing an important and valuable geoheritage. The Ligurian regional law (L.R. 39/2009) protects and enhances geodiversity and geosites, establishing the Regional Inventory of Geosites; however, an approved official inventory is still lacking. In this work, a first reasoned inventory of 120 geosites is proposed for the Liguria Region on the basis of field surveys and literature review. A quantitative assessment of the value and the degradation risk of geosites has been carried out: the value assessment takes into account scientific, additional and potential-for-use values; the degradation risk assessment considers geosites’ fragility and vulnerability. The results, providing knowledge on the Ligurian geoheritage, can serve as the basis for the Regional Inventory of Geosites and can be useful tools for the implementation of any regional geoconservation strategy or environmental management plan.

Novel Coronavirus

The novel coronavirus (COVID-19) outbreak is a public health emergency of international concern, and this emergency led to postponing elective dental care procedures. The postponing aimed to protect the public from an unknown risk caused by COVID-19. At the beginning of the outbreak, for public health authorities, the aerosol-generating procedures and the close proximity between dental care workers and patients in dentistry represented sufficient justification for the delay of dental visits. Dental care is a priority, and for many years, studies have proven that the lack and delay of dental care can cause severe consequences for the oral health of the general population, which can cause a high global burden of oral diseases. Safety is necessary while resuming dental activities, and risk assessment is an efficient method for understanding and preventing the COVID-19 infectious threats facing the dental industry and affecting dental care workers and patients. In this study, for safe dental care delivery, we adapted risk assessment criteria and an approach and an occupational classification system. Based on those tools, we also recommend measures that can help to minimize infectious risk in dental settings.

Biofilms form rapidly on dental unit waterlines. The majority of the organisms in the biofilm are harmless environmental species, but some dental units may harbour opportunistic respiratory pathogens. This paper describes a risk assessment approach to analysing the hazard from biofilm organisms contaminating dental unit waterlines on the respiratory health of both the dental team and patients. The health risk from the respiratory pathogens Legionella spp, Mycobacterium spp and Pseudomonads was found to be low. Nevertheless, in order to satisfy water regulations and comply with health and safety legislation dentists should institute infection-control measures to maintain the dental unit water at the standard of less than 200 colony-forming units per ml of aerobic bacteria.
